I had massive issues with the first Darksiders (as did plenty others) even with a machine that could handle it. There was NO support for it, no developer feedback, no patching, nothing. In the end I just pirated it (AFTER paying for the game that is, and the pirated version works perfectly) and let's just say I won't give them any more money again. The Witcher II is highly praised and for the little I have played it seems like a solid RPG type game. On the other hand, you have Fallout 3 for big epic games..
